Work just like they should! No problems

Minus a full star b/c of no docs. It works fine BUT don't use it with the raspberry pi pico, get a Songle SRD-03VDC-SL-C instead so you can work with 3.3 V of the pico's GPIO.

Works perfectly for Arduino. The ones I got were 5V versions so the 5V Arduino power supply also works for the DC+/- connections to activate the relay (though may not be ideal for your octoplur allocation if you want that specifically).My only gripe is that this is overkill for simple applications where you just need a relay circuit, but for the price, it works great.
